DETACHABLE TEII'ETH FOR GEAR-WHEELS.

Be itknow'n that I, FRANK L. MORSE,"&

citizen of the United States, and a resident of Trumansburg', in the county of Tompkins and'State'of New York, have inventeda certain new and useful Improvement in Detachable-Teeth for Gear-Wheels, of which the f 01 lowingisa specification. 7 I

This invention relates to detachable teeth for sprocket-wheels for chain gear-wheels,

. and-especially to detachable sprocket-teeth for chain gearing. Its principal object is the formation or gear-teeth in a manner such that-the gear-Wheels may be constructed at,

a lesscost than heretofore and at the same time may'be.- readily repaired byreplacing worn teeth by. new ones.

Another object is the -provision of detachable gear-teeth, especially sprocket, that may be readily applied, to wheels of various sizes. i

With these objects in View the invention ing.

n the accompanying drawings, which form a part ofthis specification, Figure 1 shows in side elevation a portion of a sprocket- -wheel involving my invention.

Fig. 2 represents the same in plan view. Fig. 3 illustrates a modification in the series of sprocketteeth. Fig. *4 is a vertical section through one -of 'saidteeth, taken on the line 4 4 of Fig.

'3. Fig. 5 shows another modification in a Fig. 6 18 a trans verse section through ,the strip or series of series of sprocket-teeth.

sprocket-teeth shown in Fig. 5, taken on the line 6 6. Fig. 7 shows inside elevation another formation of sprocket-teeth as mounted :on a portion ofa wheel. or pulley. Fig. 8

shows in plan a portion of theseiics of teeth seen in Fig. 7. Figs. 9 and 1() illustrate details of the series of teeth seen in Figs. 7 and 8. Fig. 11 shows in side elevation a further modification in a series of sprocket or ear teeth. Fig. 1-2 shows in plan a portion oFthe teeth seenin'Fig. 11. Figs. 13 and 14 show details of the teeth seen in Figs. 11- and 12.

In carrying out the invention above outlined a series of teeth are formed in any suit- Specification of Letters Patent. Application filed April 2. 1201.] Serial No. 54,018.

able way and said series attached byv riveting or other means-to the periphery of a wheel or pulley. In Figs. 1 to 6 a flexible strip of sprocketteeth is shown, in which the teeth are struck u from sheet metal, which is then riveted to t e periphery of the Wheel or ,pul-

ley thatlis to be equipped with teeth. As

shown in Figs. 1 and 2, a strip of sheet metal, as .17, has had struck up therefrom alon its middle line a series ofprojectionslS, w ich shall serve as teeth when said strip is put in place. In Fig. lthis strip is shown as mounted u'pon the periphery of a wheel, as 19, and

secured thereto by means of rivets 20, in' this manner forming either a gear or sprocket wheel. cated upon 'a straight bar and a toothed rack formed thereby. The plain strips left at the sides of the succession of teeth serve as a basepiece for securing the teeth in place,'.whether on a straight bar or on the periphery of a wheel. In Fig. 3 the teeth 18 have been provided with guides for a drive-chain by striking up portions of the metal from the ends of said teeth, as seen at 21. Ifpreferrred, guides Obviously this strip might be 10- for the drive-chain may be formed at the ends of the valleys between the teeth; as

shown at 22 in Figs. 5 and 6., In either of these forms just described the guides may be constructed at the time the teeth are formed.

Instead of making the removable gear or sprocket teeth from sheet metal with ortions thereof struck up as just described, t ey may be made from parts or pieces united together substantially as'shown in Figs. 7 to 14, the production of a flexible ban of gearteeth being efl'ected in either way.

In Figs. 7 to 10 a flexible removable band of s rocket-teeth is shown as madeup of bloc 24, on which the teeth are formed,

dovetailed together at their bases and perfo rated longitudinally of the teeth, as ,at25, for the reee )tion of a pin or rivet, said blocks being hek together, in airs by plates 26, and said pairs-being held together by links 27. A band of teeth formed in thisinanuer'niay be mounted upon a wheel or ulleylQ, and

the ends thereof joined by lin s 27, and the band of teeth'thus constructed.prevented from creeping on said wheel or pulley by suitable stops or screws passed throug 1 t 1e periphery of the iplley into theblocks 24, as in-' dicated at 28,. ig. 7.

In Figs. 11 to 14 a flexible band of sprocketteeth is shown, made from plates 29, stam )ed, swaged, or otherwise produced in the orm illustrated, pin or rivet holes, as 31, being provided at the ends of the base for securing provide an additional height for said guides.

Other modifications than those above specified may be made in the form and construction of removable sprocket-teeth without departing from the spirit of my invention.

1 claim as my invention-- 1. An article of manufacture comprising a flexible band of sprocket-teeth having lateral extensions on each side from the base of said teeth, said lateral extensions forming plain fiat base pieces or flanges adapted to be bent around and secured to the periphery 01" a wheel.

l I 2. An article of manufacture comprising a flat flexible metal strip having a line of hollow gear-teeth formed through the center thereof, and plain flat base pieces or flanges extending laterally from the base of said teeth. a

3. An article of manufacture comprising a flexible band of sprocket-teeth provided with guide-pieces along the edges of the line of gear-teeth, whereby lateral movement of a drive-chain on said teeth is prevented.

4. An article of manufacture com )rising a metal strip havin a line of gear-teet formed thereon, the teetr being provided at their ends withproj ecting guide-pieces for a powerchain.

5. The combination with a wheel or pulley, of a flexible metal strip having a line of gear teeth formed thereon, base news or flanges extendin laterally from the base of said teeth and detachably secured to the periphery of said wheel.

6. An article of manufacture comprising a flexible band of sprocket-teeth adapted to be placed around and secured to the eriphery of a a heel, and guides along the sides of the line of teeth for preventing lateral displace ment of a power-chain.

Signed at Trumansburg, in the county of Tompkins and State of New York, this 28th day of March, A. D. 1901.
